BTD 800 USB

The BTD 800 USB dongle is in combination with the PRESENCE™ UC ML, PRESENCE™ Grey UC, MB Pro 1 UC, MP Pro 2 UC or MB 660 UC a solution that is compatible with leading UC platform providers such as Cisco, Avaya and IBM. This powerful combination provides you with a high-end solution that lets you maximize the potential of your Unified Communications. When used with the SDW 5000 Series base station, it provides connectivity to mobile devices.

Plug n’ play
The BTD 800 USB provides your computer with a rapid Bluetooth® connection to the headset without requiring any technical installation. This ensures an excellent voice and sound experience.

Increased range
Now you can get the freedom to move up to 25 meters / 82 feet from your PC with dongle – depending on device and environment.

Security
The BTD 800 USB exclusively supports audio, therefore no data exchange is possible making it very secure.

3) Purple LED blinks 3 times. The purple blinks are quite rapid and may be missed.

4) Pairing list has been cleared and the device re-enters pairing mode.

NOTE: Once a factory reset has been done it cannot be re-done until the headphones have been paired to at least one device.

Why is there an audio delay when using a BTD 800 dongle?

Sometimes when utilizing the BTD 800 Bluetooth dongle there may be a delay in the audio transmission.

The delay on Bluetooth speech/microphone transmission is caused by how the PC is utilizing the audio information it is being provided. For example when using a Bluetooth headset (ie: PRESENCE or MB Pro 1 or MB Pro 2) and a Bluetooth Dongle (ie: BTD 800) in communication mode the two (2) devices toggle from the A2DP profile to the Handsfree Profile in order to run full duplex audio (this is not possible in A2DP). Here the latency is at about 20-40 m/s whereas the A2DP has latency of about 120 m/s so the issue is not latency.

When Bluetooth Dongle (ie: BTD 800) is introduced for the PC the PC only sees it as a sound card with input/output and the usage of these interfaces chooses the profile to be used between the dongle and the headset. The Handsfree profile is activated when it sees activity on the microphone path (communications). Hence when there is a delay in the microphone audio the problem MUST be within the PC platform and how it chooses to use the audio resource. The way to alter/resolve this would be to adjust the PC settings and how it interfaces with the Bluetooth Dongle.

Bluetooth Dongle

A Bluetooth dongle is a device used to provide a Bluetooth connection to a device that does not have inherent Bluetooth capabilities (via a built in Bluetooth chip) or does not have the appropriate Bluetooth capabilities.

Why is there an audio delay when using a Bluetooth Dongle?

Sometimes when utilizing a Bluetooth dongle (like the BTD 500 or BTD 800) Bluetooth dongle there may be a delay in the audio transmission.

The delay on Bluetooth speech/microphone transmission is caused by how the PC is utilizing the audio information it is being provided. For example when using the MM 500-X + BTD 500 in communication mode the two (2) devices toggle from the A2DP profile to the Handsfree Profile in order to run full duplex audio (this is not possible in A2DP). Here the latency is at about 20-40 m/s whereas the A2DP has latency of about 120 m/s so the issue is not latency.

How does the Surround Sound adapter work?

The USB adapter on the headset does not create surround sound (this is a common misconception). What the USB card does is take a surround sound signal created by the audio source and decodes it to reproduce a virtual surround sound in the headset.

For example if you're playing a game and it has a surround sound soundtrack the headset can take that signal in and decode it to work properly with the headset. NOTE: The option to select the surround sound is only available if the game supports surround sound. If the game does not have a surround sound then the surround sound option is not able to be selected.

NOTE: Selecting the headset as the playback device is done within the computer settings and selecting the sound format would be done in the game itself.
